Recently I reviewed some first posts. One post's formatting was pretty bad, so I choose "Edit", to improve it. On Stackoverflow I do not have to add a summary, because I've got enought reputation. However I forgot to fill in the summary in here, so the editing page informed me with a shaking dialog to fill it in.

Maybe you are able to reproduce it!
